Claims (10)
- エンジンケーシングの一部を形成する第1のリング(23)を第1のリングと同心である第2のリング(21)の内側に懸架することに適用される連結棒の不静定トラスにして、連結棒(140;240;340;440)が、一方の端部によって第1のリング(23)に、他方の端部によって第2のリング(21)に固定された、不静定トラスであって、連結棒(140;240;340;440)が、その圧縮強度より大きい引張強度を有し、前記端部間に圧縮および引張荷重を伝達するように設計された1つまたは複数の部分(141;241;341;441)と、前記端部間に引張荷重のみを伝達するように設計された1つまたは複数の他の部分(142;242;342;442)とを備えることを特徴とする、不静定トラス。
- 連結棒(140;240;340;440)が、圧縮および張力に作用することができるように設計された内棒(141;241;341;441)と、内棒を取り囲み、張力のみに作用する側板(142;242;342;442)とを備える、請求項1に記載のトラス。
- 連結棒の内棒および側板が、内棒に張力がかけられたときに互いに押し付け合う表面の対(141a,142a;241a,242a;341a,342a;441a,442a)を有し、引張荷重は、このとき、内棒および側板によって2つの端部間に伝達される、請求項2に記載のトラス。
- 連結棒(440)が、棒の軸に沿って分散された荷担面の少なくとも2つの対を備える、請求項3に記載のトラス。
- 連結棒(340)が、圧縮応力にさらされたときに内棒が座屈することを防止するために側板の内面に対して半径方向に押し付ける手段(345)を備える、請求項2から4のいずれか一項に記載のトラス。
- 内棒が十字形の断面のものである、請求項2から5のいずれか一項に記載のトラス。
- 内棒(241)が、ねじ切りされ、軸方向に移動可能でありかつ荷担面を形成するプレートを備える、請求項2から6のいずれか一項に記載のトラス。
- 連結棒の側板(142;242;342;442)が、連結棒の軸に垂直な空気力学的プロファイルを備える、請求項2から7までのいずれか一項に記載のトラス。
- 第1のリング(23)に対して接線方向に三角形に配置された6本の連結棒を備える、請求項1から8のいずれか一項に記載のトラス。
- バイパスダクトを形成する環状ダクトと、ケーシングリングを有する排出ケーシングと、バイパスダクトの側板内の同心リングとを備え、請求項1から9のいずれか一項に記載のトラスが2つのリング間の連結をもたらす、フロントファンエンジン。
